Answer 2

the transmissions hold up pretty well in those we pull a one car , car hauler with it always loaded and it never does give any problems,so far the transmissions aren't giving very many problems at all,we use this one for everything,from pulling a hay wagon loaded down to pulling a car hauler and it never causes any problems,good luck.
